Guess their surfboards will have to be shipped!Kristen Stewartand Robert Pattinson skipped out on attending the Teen Choice Awards 2013 at the Gibson Amphitheatre in Universal City, Calif on Sunday, Aug. 11 -- despite winning numerous awards.

The Twilight costars, who ended their real-life, four-year relationship in May, were noticeably absent from this year's award show. The Twilight Saga: Breaking Dawn - Part 2 -- the fifth and final film in the saga that made them superstars -- won a total of seven awards, but none were handed out during the ceremony.

Rumors began circulating that Us Weekly was preparing to publish an explosive story that Stewart had been caught cheating on Pattinson with director Rupert Sanders. On July 24, Us released an exclusive set of photos of Stewart's makeout session with Sanders in Los Angeles, which led to Stewart's public apology to Pattinson.

Nearly one year later, the Twilight twosome decided to end their relationship after being unable to move past the cheating scandal. "He really put her through the ringer," one insider told Us of Pattinson. "Ultimately, it was like, 'Either we move past this or we don't.' It wasn't good for either of them."
